This new class is a helper for fast/tricky copy of surfaces. First it tries to copy using the function vaCopy in libva 1.12. If it fails, or it's not available, a GstVaFilter is tried to be instantiated with the allocator's parameters, and if succeed, it's used for copying the source surface. This is required for dmabuf surfaces with drm modifier. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1023>
